Thermal protection relay JR36

1 NO/NCthree-phaseAC

JRS36 series bimetal type thermal over-load relay is suitable for the circuit of AC 50Hz, rated operating voltage Ue: AC 690V, current of 0.25～160A, as the use of over-load and break phase protection for the AC motor. Thermal relay has the functions of the setting current is adjustable, temperature compensation, break phase protection, optional selection of auto-reset and manual reset, it can check the circuit's action flexibility, and can manually break the NC contact (NO contact close), its external dimension and installation dimension is the same with JR16B, which is a new generation of ideal product. This product confirms to: GB14048.4, IEC60947-4-1 etc. standards. Normal operating condition and installation condition 3.1 Ambient temperature: -5ÿ~+40ÿ, and the average value within 24h does not exceed +35ÿÿ 3.2 Altitude of the installation place does not exceed 2000m; 3.3 Atmosphere condition: The relative humidity does not exceed 50% when it is at +40ÿ, it allowed relatively high humidity at the relatively low temperature, for example, the relative humidity reaches 90% when +20ÿ, and it should take special measurements when there produced the condensation on the product due to the temperature variation. 3.4 It should be at the no explosion danger medium, and the medium without the gas that cannot corrode the metal and damage the insulation as well as the places that without conductive dust. 3.5 Grade of pollution: 3 3.6 Installation category: III 3.7 Installation position: installed at the normal position, the gradient between the installation side and the vertical side does not exceed ±5°, and without obvious vibration and impact. 3.8 Protection grade: IP 20
